Swift: AppStore - Integrating REST API, JSON, and Model Objects (Ep 2)

For the API calls, please use these two links:

In this video, we go over an example of how a real world application integrates with a REST api to retrieve data. By the end of this tutorial, you'll be able to build an application that is very similar to what the Apple App Store looks like.

I'm really looking forward to programming using Swift, I'm sure your videos will become a large asset for me in the future; thanks!

Hi Brian, the way you explain is really amazing.

[vzufusf]

I actually did the single/two line solution towards the end of the video with constraints and it worked perfectly.

Hey Brian Thanks for all your hard work and the details you include in your videos! I have a question: for each app if I don't want it to be dynamic could I just use the static function you use in the model? I have set icons and labels for each horizontally scrolling cell. The user would not be able to change them but would click them to get to another page. Thanks!

Thanks for very good tutorial with Model Object. I'm going to apply it to my project.

HI, loved your coding style.. So... clean.. One small suggestion . Instead of :
if let a = X?.a {
aa = a
}
if let b = X?.b {
bb = b
}
you can do it as

if let a = X?.a,
b = X?.b {
aa = a
bb = b
}

It becomes more readable.. :)

Keep uploading more videos..

Will you make another video similar to this or recreate this video in swift 4?

Hi! Brain. Your vids are great, but two questions. We do you import UIKit to your model? Shouldn't the business logic be independent from the UI? Why do you choose to use class for your models instead of structs (reference vs value types)?

Hey Brian, how you doing? Great tutorial as always.

I’m relatively new to iOS development and your tutorials are helping me a lot.
Right now now I’m facing a small problem and I can’t seem to figure out how to solve it.

I’m building an app that implements most of the features you have on your AppStore Clone App.

On my App, the user can choose which categories he wants to see everytime he runs the App.
Sometimes according to some filters like [Date], certain categories may not have results to be shown. e.g.: He picked categories A, D, F, G and M. But for today, only D, F and M satisfies the criteria.
The problem is, In my UICollectionView I want to implement the numberOfSections and numberOfItemsInSection methods according to the above, with header titles, etc.

Mentally I can go through the necessary logic to achieve that, like, return the count considering only those categories with at least one item. But I’m having troubles to translate it to swift code.
How should I approach it? Can you share a code snippet implementing that?

Thanks in advance.

can u help me? I'm using swift 5 and It's appear "Value of type 'Any' has no subscript" in for dict json["categories'] how can I fix that?

[GillesVandenPeereboom]

Really like your code only approach in your videos.
Do you use still use storyboards in some cases?

[alexsalgado]

Hi, Is there a way to download and show the icons in realtime ?

[garrettosborne]

Hi Brian, Liked the video and am glad I subscribed. What is the first part you talk about in the video? Can't seem to find it.

[tahirify]

hii brian ... i like your tutorials...Can you give an example of how to implement MVP architecture into and iOS application ..
